TABLE OF ANOMALIES AND REMEDIES
The interventions must be carried out by a qualified installer or by a specialised service centre.
Effect
A delayed activation of the ventilation
respect to the new temperature or function
settings.
The ventilation speed increases or
decreases automatically.
The appliance does not activate the
ventilation.
The ventilation does not activate even if
there is hot or cold water in the hydraulic
circuit.
The appliance leaks water during the
heating function.
There are formations of dew on the front
panel.
There are a few drops of water on the air
outlet flap.
The appliance leaks water only during the
cooling function.
The appliance makes a strange noise.
FI: The fan coil unit requires maintenance,
select the stand-by program, clean the air filter
as described in the maintenance manual, and
the next time the unit is switched on, hold down
keys
(fig. 1 ref. B1 and H1) for 5 seconds
until normal operation is resumed.
E2: signals that the ambient temperature probe
is faulty.
E3 is associated with the water probe fault.
E4 signals a fault with the motor or the speed
sensor. In the second case the appliance runs
normally but the fan speed modulation function is
inhibited; pressing keys
(fig. 1 ref. B1 and
H1) for 10 seconds will cancel the alarm signal.
E5 signals a communication fault with the
remote control

P
Cause
- The circuit valve needs some time to
open and as a result the hot or cold water
takes time to circulate in the appliance.
- The electronic control adjusts the
comfort level regularly.
- No hot or cold water in the system.
- The hydraulic valve remains closed.
- the fan motor is blocked or burnt out.
- the electrical connections are not correct.
- Leaks in the hydraulic connections of
the system.
- Leaks in the valve unit.
- In situations of high humidity (>60%)
condensation could form, especially at
the minimum ventilation speeds.
- The condensation bowl is blocked.
- The condensation discharge does not
need an inclination for correct drainage.
- The connection pipes and the valve unit
are not insulated well.
- The fan touches the structure.
- The fan is unbalanced.

Remedy
- Wait for 2 or 3 minutes to open the circuit
valve.
- Wait for the temperature adjustment or
in case of necessity select the silent
function.
- Check that the water boiler or cooler
are functioning correctly.
- Dismount the valve body and check if
the water circulation is restored.
- Check the working efficiency of the valve
by powering it separately with 220V. If it
activates the problem could be the
electronic control.
- Check the windings of the motor and the
free rotation of the fan.
- Check the electrical connections.
- Check the leak and fully tighten the
connections.
- Check the state of the gaskets.
- Check the correct positioning of the
thermo-acoustic insulation paying
attention to that in the front above the
finned battery.
- As soon as the humidity starts falling
the phenomenon disappears. In any
case the presence of a few drops of water
in the appliance does not indicate a
malfunction.
- Slowly pour a bottle of water in the low
part of the battery to check the drainage;
if necessary, clean the bowl and/or
increase the inclination of the drainage
pipe.
- Check the insulation of the pipes.
- Check for any interference by manually
rotating the fan.
- The unbalancing causes excessive
vibrations of the machine; replace the
fan.
